■关节镜前交叉韧带重建术（ACLR）后的并发症很少见，但是有可能会损伤the动脉.静脉假性动脉瘤是一种潜在的并发症，如果不及时诊断和治疗，可能会导致严重的发病率。
■我们描述了两名患者在关节镜ACLR后出现神经损伤的情况，随后诊断为pop动脉假性动脉瘤。两种情况下腓骨神经都能自发恢复，使用自体神经移植重建胫神经。满意,术后24个月观察功能恢复.
■迅速诊断和有效治疗pop动脉假性动脉瘤对于防止进一步的并发症至关重要。然而,由于临床表现不一致和怀疑指数低,及时诊断可能具有挑战性.本病例报告强调需要提高对这种罕见并发症的认识，并提供对其病理生理机制的见解。
UNASSIGNED: Complications following arthroscopic anterior cruciate ligament reconstruction (ACLR) are rare, but injuries to the popliteal artery can occur. Popliteal pseudoaneurysms are a potential complication and can cause significant morbidity if not diagnosed and treated promptly.
UNASSIGNED: We describe the cases of two patients who developed nerve injuries following arthroscopic ACLR, with subsequent diagnosis of a popliteal pseudoaneurysm. The peroneal nerve recovered spontaneously in both cases, while the tibial nerve was reconstructed using autologous nerve grafting. Satisfying, functional recoveries were observed 24 months postoperatively.
UNASSIGNED: Prompt diagnosis and effective treatment of popliteal pseudoaneurysms are crucial to prevent further complications. However, timely diagnosis can be challenging due to inconsistent clinical presentations and a low index of suspicion. This case report highlights the need for increased awareness of this uncommon complication and provides insights into its pathophysiological mechanisms.
